This is weird because I have played Nocturne before and it was completely fine then. No emulation settings seem to have any effect on this, however if I reboot the game (fast) at this point, the TLB Miss log gets shorter the next time it freezes. After a few crash-reboot cycles the game suddenly runs completely fine. This is incredibly annoying and time consuming. No, my disc image is fine, it worked fine before. No, I am not using cheats and I am not using savestates.

I'll try to dig out my DVD, in the meantime I tried to mount the disc image in Windows itself and run that image via cddvdGigaherz. The game ran fine, but froze some twenty minutes later when I tried to save the game (selected save, screen went blank and stayed blank).
